While practical constraints may limit the value of filter_index to remain within
the bounds of a positive signed int, there is certainly no such guarantee here.
Also, a plain majority vote suggests that this really just a wrong declaration
in link.c as several declarations of filter_index as signed int exist.

My followup on this was:
I think the majority is wrong.
filter_index is assigned exclusively from if_nametoindex or ll_name_to_index
which both return unsigned int.
Changing it to unsigned everywhere seems better.
This has been minimally tested by using the bridge tool
to add vids and showing available vids on different devices.
